No ignite attempt by hot water heater
Have a brand new 2891BH, have used the gas water a dozen times and this pm went to light it at the wall and no red dsi lite or clicking heard. Ignitier is not igniting. any one have any thoughts on this? I have electric hot water so good there. Have checked connections and they all look good. No rust or build up seen anywhere, it is new. Any one else? Thanks. Scott

If on electric and water is hot, then propane will not light until hot water is used and thermostat is calling to heat water.

This happens a lot, especially for those (like me) that use both for quick heat recovery. Always want to check that first.
After all the typical possibilities have been eliminated, you might want to give this a look.

Could be the computer board for the igniter. We have a 2018 Forest River 27REI with a Suburban water heater and ours had the same issues in the spring. It had to be replaced. Such a short time and the piece failed already. Sad

try this maybe?
I've had the same thing happen, I have hot water with shore power but not with gas, so I make sure propane is on, and I light my indoor stove burner for a few minutes. I think it pulls the gas thru the lines, and then I try the hot water heater and it has always worked! someone with more experience than I have told me to do that..

The gas side of a hot water heater usually depends on 12 VDC for ignition. Check batteries.

And check the 12v fuse for the heater.

There are two limit switches that can trip, one for propane and one for electricity. Each is under a black rubber disk on the outside face of the water heater. They look like Mickey Mouse eyes. Push each one firmly. You can tell if each needed resetting.

I had the same problem last year. Turns out one of the wires going to the control board for the heater had disconnected... Quick no-cost fix.

If the electric side is on...."Shut it OFF"....Turn on a hot water faucet and let it run for a few minutes. Leave the electric side OFF and then turn on the propane side and see if it lights. As posted before....if the water is HOT !!! the propane side is not going to run.

the OP said the rocker switch didn't light up when he turned it on, that would indicate no power or no ground at the switch.

So let me follow up on this. It was totally on me. To remind everyone, I would have the light at the rocker turn on but no clicking like calling for the burner to ignite. I turned on the electric heater had plenty of hot water and then sat there thinking about it for a couple of hours. Then it hit me. We already had hot water. We had used it about 2-3 hours prior to restarting it, the tank had hot water in it and when I flipped the rocker the temp of the tank was over 100 degree's so there was no call to heat. I'm a dummy. left it all off overnight, made sure the water tank cooled and the next am the heater lit like brand new. No problem, all my expectations were wrong, that's all. Thanks for everyones input.

OK, I understand that the OP has figured out the problem. I am only posting this as an addendum to those who may run across this thread in future searches for similar problems.

Just to clarify, the OP stated the red dsi light failed to come on, not an illuminated rocker switch. These are two different things.
The DSI fault/reset lamp is explained in post #5 in this thread:

Also a beginning troubleshooting method for the propane portion of a Suburban brand tank type water heater is explained in this thread starting at post #6 and reading forward
